Hi,
Is there any way in yt to get a script to delete (or ignore) all the .yt
and .harray files and clear its memory? I run into errors when I'm
re-doing a plot or I've re-run the simulation and over-written the last
data set I looked at with yt. I have to exit yt, delete the above files
by hand and restart, which is a bit of a pain.

Hi all,
I'm not sure if this is the right list to send this to, but I think a
bunch of knowledgeable people read this one, and hopefully one of you
can help me. I'm trying to use Reason and I'm kind of confused about
the ssh tunneling part. I start up yt serve on a remote machine
(ranger) and I'm told to create a ssh tunnel by executing these
commands:
~C
-L55185:localhost:55185
My local machine doesn't recognize "~C" and I'm not sure what it is
either. I tried creating an ssh tunnel with this:
ssh tg803911(a)ranger.tacc.utexas.edu -L 55185:localhost:55185
I was then able to successfully open the gui in a browser with the url
provided, but I am unable to load data (I can view the help though). In
order to do the ssh tunnel properly do I need to install something on my
local machine?

Hi all,
yt is in need of an awesome new logo, which is why we are announcing the
first ever new logo contest! So here's the deal:
We'll accept entries for the next two weeks. Let's arbitrarily say Tuesday,
May 10th, at 11:59:59 pm EST. If there is more than one entry, we will put
it up for a community vote at that time.
Oh, and the most important part -- the winner will get a coffee mug with
their new logo front and center!!!
Please email yt(a)enzotools.org with your image attached. Good luck, and happy
logo-ing!

Hi all,
I am using FLASH3.3, testing the (3D) spherical coordinate system.
Is it possible with YT to make a slice with this kind of coords (r,theta,phi)?
If so, how can I do that? Could you provide a template?
Thank you in advance,
Massimo Gaspari

Hi Matt,
thanks a lot for your reply! Of course, I am aware that you cannot
account for every special situation in the design of yt right from the
beginning, so sometimes we have to resort to provisional solutions.
I followed the procedure you suggested on the machine behind the
firewall (I think there was a confusion of A and B - never mind;-).
After removing and re-creating the yt-hg subdirectory and changing into
this directory, the execution of
~/yt/bin/hg unbundle ~/yt/yt-20110428.hg
yielded the error message:
abort: There is no Mercurial repository here (.hg not found)!
Now, one thing is for sure: yt-20110428.hg is right where it is supposed
to be:
ls -l ~/yt/yt-20110428.hg
-rw-r--r-- 1 lu78tar3 pr47bi 25682789 2011-04-29 19:18
/home/hlrb2/pr47bi/lu78tar3/yt/yt-20110428.hg
So that's curious...

Hi everyone,
I just tried a new install of yt on kraken form the install script. It
failed on installing h5py 1.3 with the following error:

I checked that the kraken yt install from the yt module is using h5py 1.2,
which I believe suffers from the h5py bug that was mentioned not too long
ago. I double checked that I had gnu compiler module loaded, so I don't
think that's it. Does anyone have any ideas?

Hi everyone,
perhaps, others also have encountered the situation of having to install
yt on a machine with tight security measures that do not allow access to
the internet through its firewall.
An awkward, yet doable workaround is to mount the installation directory
via sshfs on a machine outside the firewall (let's call it machine B) to
download the required packages and to execute everything else on machine
A behind the firewall.
With the most recent yt version, I encountered a problem once the
installation of Python was completed. Going back to machine B to
download the yt distribution, I found that the previously installed hg
wouldn't work. The last lines of the installation log (see attachment)
show that hg, running on machine B, attempts to use Python under the
path that applies to machine A (/home/hlrb2/pr47bi/lu78tar3/yt/...
instead of /home/raid2/schmidt/hlrb2/yt/...), athough I set DEST_DIR to
the (sshfs-mounted) path that applies to machine B. What should I do
about that?
Cheers,
Wolfram
